Veteran Cardinals right-hander Chris Carpenter, who's missed the entire 2013 season to date because of back and shoulder problems, made a minor-league rehab start for Double-A Springfield on Monday.

Carpenter allowed three runs, two of which were earned, and struck out five against Double-A Arkansas. Of his 54 pitches, 38 went for strikes. While the pitching line wasn't optimal, Carpenter's velocity certainly was. As Derrick Goold of the St. Louis Post-Dispatch reports, Carpenter, according to a team official in attendance, touched 94 on the radar gun.

As Goold notes, Carpenter, per MLB rules regarding minor-league rehab assignments, will have 30 days until the Cardinals must either place him on the active roster or return him to the disabled list.

Carpenter, age 38, has a career record of 144-94 across parts of 15 major-league seasons. Over that span, he's pitched to a 3.76 ERA (116 ERA+).
